Rototrode® non–consumable melting

The Rototrode® is a unique, non-consumable melting system for the melting and recycling of reactive and speciality metals

The Rototrode® system melts vacuum melted metals and related alloys in a single operation.

Rototrode® utilises a rotating, water-cooled copper, non-consumable electrode to melt vacuum melted metals and related alloys in a single operation. Melting is performed by a high current DC arc. The main advantage of this technology is that it allows direct feeding of a wide range of raw materials.

Rotorode® non-consumable melting is used in both aerospace and commercial applications and in recent years this innovative technology has been applied to casting VAR bar stock and powder as well as near net shape products.

The technology can be applied to tilt-pour crucibles for parts casting, static crucibles for ingot production or bottom-pour crucibles for powder production. Complete alloying and melting are enhanced by the furnace’s ability to achieve and hold higher pool temperatures for controlled periods of time. Ultimately, most forms of scrap can be readily upgraded to ingot quality.
